No, directly vents through to outside wall of building.
Return air vents.........
Cold air return vents are the ones on the wall
smoky mist coming from the heater vents.
The heater may not be on - but the fan still blows air through the vents when they're open !
There are heater doors on the heat blower box that direct the path of the heat. Apparently the heater door to the floor vents is stuck closed.
heater fan broken.
Could be that your heater core is leaking May also have a plugged evaporator hole.
More than likely you will not have heat being the water wont be circulating through the heater core , When the hot water passes through the heater coil the air passing through the heater coil makes heat blow out the vents when you have selected a heat setting on your controls.
